CHALK IHOLDIEH,

SPECIFICATION forming part of Letters Patent N0. 777,522, dated December13, 1904.

Application filed May 28, 1904: Serial No. 209,277. llio model.)

To all whom it 'III/H/Z/ concern:

Be it known that we, ADoLrrI LINKS and BENJAMIN KRAUs, citizens ortheUnited States, residing in the city and county of San Francisco andState of California, have invented new and useful lm provemen ts inChalk-Hold ers, of which the following is a specification.

Our invention relates to improvements in chalk or marker holders "foruse by tailors and the like.

its object is to provide a simple, cheap, and practical holder andprotector for the chalk or marking substance.

The invention consists of the parts and the construction and combinationof parts, as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure 1 is aperspective view of single holder. Fig. 2 is a section through same.Fig. 3 is a perspective view of double holder. Fig. 4 is a sectionthrough protector. Fig. 5 is perspective view of same with one sideremoved, showing sharpening device.

A represents our holder, made from a single piece of spring sheet metalbent centrally upon itself and having a width about equal to thatof theusual tailors chalk. The gripping ends of the holder are normallypressed together, but are readily separated by pressure on the buttons2, which have their stems secured one to one jaw and projecting througha hole or slot in the opposite jaw and the other secured to the latterjaw and projecting through the first-named jaw. By simultaneouslypressing in on both buttons the jaws open; releasing the buttons thejaws close.-

The jaws are each slotted transversely adjacent to their ends, as shownat 3, and the edges of these slots are-turned in slightly to form broadsharp teeth which bite into the chalk and keep it from wabbling orslipping when being used. By slotting the jaws in this manner twowidely-separated grippingsurtaces are provided on each side of thechalk.

In Fig. 3 is shown a modification of the invention in the form of adouble holder where it is desired, as is frequently the case, to use twochalks of diflerent colors. .111 this case the same kind of a holder aslirst described is en'lployed, to which the opposed coactingspring-clips i are secured by means of the rivets or otherwise. Theseclips are slotted similarly as the jaws of the holder A and areseparated by means of the buttons 2.

In order to preserve the chalk when not in use, we employ a protector orcap which comprises two thin spring-plates 6, secured togetherintermediate or their ends and adapted to be slipped over the protrudingend of the chalk in the holder and to embrace the sides of the latter.The opposite ends of the plates may be flared outwardly, as at 7, andbetween these flared ends is contained a V- shaped sharpener 8, butforming no part of the present invention.

The object of the spring-caps is to protect the )rotruding end of thechalk in the holder A from breaking when lying on the table, as byhaving a bolt of cloth or other heavy substance thrown on it, and tokeep the chalk from rubbing OH in case the holder is carried in thepocket.

An instrument of this character conduces to neatness and cleanliness, issimple, needs no adjusting, holds the chalk securely, allows the chalkto be readily released and a fresh piece to be inserted, and protectsthe chalk when not in use.

It is obvious that various modifications of our invention are possiblewithout departing from the principle thereof.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

1. A chalk-holder comprising a single piece or spring metal bent uponitself to form two normally closed coacting spring-jaws approxi matelycoextensive in width with the width of the contained chalk, said jawshaving transverse slots adjacent to their gripping ends, the rear wallsoi said slots adapted to impinge upon the chalk and cooperate with theends of the jaws to grip the chalk and hold it against twist.

2. A chalk-holder comprising a single piece of spring metal bent uponitself to form two normally closed coacting spring jaws and meanscarried by the jaws for opening them,

said means including a pin on each jaw projecting through an opening inthe opposite jaw, said pins provided with buttons for engagement by thefingers.

3. A chalk-holder comprising a single piece of spring metal bent uponitself to form two normally closed coacting springjaws, said jawsslotted adjacent to their gripping ends and provided with a plurality ofseparated extended gripping edges, and means for opening the jaws.

4. A chalk-holder comprising a single piece of spring metal bent uponitself to form two normally closed coacting spring jaws, said jawsslotted adjacent to their gripping ends and provided with a plurality ofseparated extended gripping edges, means for opening the jaws, saidmeans including studs or pins on each jaw projecting through theopposite jaw and provided with means for engagement by the fingers.

5. A chalk-holder comprising two opposed normally closed spring-actuatedjaws, a stud on each jaw projecting through the opposite jaw andprovided with means for engagement by the operator whereby asimultaneous pressure on said engaging means tends to open the jaws.

6. A chalk-holder comprising two opposed normally closed spring-actuatedjaws, and a stud on each jaw projecting through the opposite' jaw andprovided with means for engagement by the operator whereby asimultaneous pressure on said engaging means tends to open the jaws.

7. The combination with a chalk holder comprising two spring-actuatedjaws of a spring-cap arranged to slip over said jaws to protect thecontained chalk.

8. The combination with a chalkholder comprising two spring-actuatedjaws of a removable protective spring-cap therefor.

9. The combination with a chalk-holder having jaws engaging the oppositesides of the chalk, of a removable spring cap or protector adapted toinclose the protruding end of the chalk and embrace the jaws.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
